3.9 RSR project --- my Carrera reborn

[eimkeith]

uncrated the engine for the 4th...





btw, you guys, we will be having an open house/going away party for Matteo and the blue IROC on Saturday, August 4th.

you are all invited!!

Sorry if I missed this earlier, but how did they get Rear Wheel Horsepower? Was the engine installed in another car for tuning and then run on a chassis dyno. I assumed Peter had an engine dyno.

Thanks

Engine dyno AND installed on a different car for fine tuning.

In fact the figure above is only indicative as it is at 7,000rpm.

The engine can spin to 8,200-8,300 and the sweet spot for the cams is 7,600rpm.

We are still waiting for the dyno sheets fro Peter but the motor should be good for 325-335 rwhp.

Anyway the priority was to get the engine here so that the car could be finished

Matteo,

Is that Timmins exhaust system - it certainly looks very neat and I guess would work well with a 73 RSR rear bumper?

Looking forward to hearing it in the flesh.

Hi Matteo,

Congratulation for your project.
You would have photographs of the reinforcements surrounded in red.

thank you in advance

Alex,

If you are looking for a reinforced engine bar, I'll be selling my old one. I just bought the one offered by Rennline if you want to get something new. PM me if you are interested.

[curtisaa]

what type of injection are you using ?? how about fuel management ??

[SCHNELE]

Motec M600 handles the EFI, see above like 30 pages ago.

[Jeff Alton]

Those are Jenvey ITB's on it as well.

Cheers

Airflow thru the motor is important - but looking at the Timmins muffler appears to be a 12" - 14" muffler......and that means that noise level is likely to be substantial. Guys here are usually saying how great it is to have a throaty roar out the exhaust - but I've always liked the factory mufflers for the job they did and did well.

It's an impressive looking sytem - but I'm wondering at 7500 rpm whether the decibels will be overwhelming - versus
the factory banana muffler.

Not a big concern, but decibel volume can wear you down eventually.

bah... this hole car is extreme, it needs to make noise to suit.

Steve's headers with heat are some of the best exhaust for a 911 you can get in my view. I agree, the muffler is too small and in fact will probably be too restrictive. Teo can deal with that later. What I did was run two mufflers back to back so that each side has its own 15 inch magnaflow muffler, and yes, I fit it under my RS bumper... and yes, I have a great exhaust guy

Looking good Bob, didn't realise it had relocated to the Lone Star State?

[Craig 930 RS]

Shore do look like a Flowmaster - you will LOVE IT.

I had one on the 3.6.......it was perfect.

[efhughes3]

Bob's in TX, but has a strong connection to the shop in N. Carolina, you might say.

Actually, the muffler does look like a FlowMaster via Fabspeed....

[Craig 930 RS]

It is. Prepare for exterior/pipe rust - more than you'd think.

Mine's almost 3 years old-no rust up to now. But that's Texas, infrequently driven in rain.
